About this example
This example is an estimate from a roofing contractor to homeowners whose roof was damaged by hail. It prices a full tear-off and a new Class 4 impact-resistant shingle roof on a two-story house with a detached-looking garage wing, 27.1 squares in all.
An estimate is not a fixed quote: some costs only show up once the old roof is off. This one handles that the way experienced roofers do. Every quantity is traced to a roof plan with lettered facets, the shingle count adds a 10% waste factor, and the decking line is an allowance for three sheets with a stated price for each extra sheet. The terms cap the final bill at 10% over the estimate without written approval, so the homeowner knows the worst case before signing. Three shingle options are priced per square, and the payment schedule asks for nothing until materials arrive.
Who it is for
Roofing contractors and storm-restoration companies who estimate residential re-roofs for homeowners, and anyone pricing work where hidden conditions can change the final quantities.
